A cargo suspension gear has a plurality of automatic hooking apparatuses which each can hook and unhook an object such as a trunnion on a large-size cargo receptacle charged with heavy cargo such as pig iron ingot or iron scrap pieces. Efficiency of the cargo handling work is remarkably improved by virtue of the automatic hooking and unhooking function and the use of large-size cargo receptacle. Working environment also is improved because there is no generation of dust.
